AllAboutTheTea.com has learned some scandalous tea — one of the women entangled in Austen’s love triad, engaged in a sex act with her crush, behind Austen’s back!

“Victoria and Shep would playfully flirt by text and phone. Nothing serious.” A source tells AllAboutTheTea.com.

“Early one morning in November, she went to Shep’s house and they got frisky. They made out and Victoria ended up giving Shep a blow job!” The source adds, “They hooked up a few more times after that.”

According to the Charleston snitch, Austen is completely in the dark about Shep and Victoria’s hook ups.

“He [Austen] has no clue what happened between Victoria and Shep. The news would crush his big ego. And Victoria is very private, so this secret going public would embarrass her.”
